XP hangs on "Applying Computer Settings"

Question

We have mixture of domain controlers running 2000 and 2008. I am experiencing performance issues our XP SP3 Pro systems. During booting up, prior to the Ctrl-Alt-Del screen being presented, the system hang at applying computer settings. I have narrowed this down to a Domain GPO that is applying a policy setting Always wait for the network at computer startup and logon. But of course this appears to not be the actual problem, it just makes the system slow down.

I have enabled debugging for userenv.

I have noticed a few lines in the log that points to be a DNS issues on the system (see below). It appears what is creating our lag at boot up is DNS unavailable. I have run several tests on the system after logging in and it appears DNS is working and available.

Does anyone have additional recommendation on what else I can try to troubleshoot or look at? If I deny the GPO with the Always wait for the network at computer startup and logon setting the system boots up fast, however I believe there is an underlying issue and the GPO is not our problem.

From the Userenv.log GetUserDNSDomainName: Domain name is NT Authority. No DNS domain name available ImpersonateUser: Failed to impersonate user with 5.GetUserNameAndDomain Failed to impersonate user

Generally speaking, this kind of issue may be caused by conflicts of software. If there is any startup software on clients machines, such as Antivirus software, Firewall, please disable them all to test. Please also test in Safe Mode with network to narrow down the cause.

If the issue persists in Safe Mode with network, please help the following information for research.
